> There are scenarios where a client will have several cache client initialization threads active (for instance, if the first thread blocked for a significant amount of time waiting for a lock). In that scenario, it is possible for two threads to create their own registration queues and only one "wins", then upon draining the queue the first thread to remove the queue can cause an NPE in the second thread because it was assumed the queue was still present.
